For Oresteia, a modern production of the Greek tragety, I was comissioned to create "a manifestation" of the Oracle. I used a projection system to create a vortex of particles on the floor and a dynmic wispy cloud on the wall. Through use of a stereo vision system, both the vortex and the cloud responded to actors' movements in the performance space. As the plot unfolded, the color pallet and intensity of the vortex shifted creating a sense of tension and foreboding.
